* Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor. Place the windows above the TV windows for each scope you are using. They should show white sine waves that are around the height of the window. Erratic, fluctuating waves indicate self-interference or a weak signal. This may cause the carts to lose their place as the signal strength falls too low. Red waves indicate that some displayed signal has gone too low and the carts will all need to be homed. A careful adjustment of the MET2 mirror can sometimes bring the signal back. Do not adjust the MET1 mirror. | * Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor.

* To home the carts, turn off the [OL] and [MAN] buttons on each cart and it will automatically return to the front switch. If the cart has no issue, it will arrive at the target position of 0m and the home switch at the same time. The X in the OPLE server under the HM will indicate it has homed to the home switch. If a cart does not reach the home switch when it returns to position 0m, it was lost and likely the cause of the difficulty in finding fringes. Hit the [HOME] button and it should move forward and trigger the home switch. Hit [TRACK] to home it to the new home position. | * To home the carts, turn off the [OL] and [MAN] buttons on each cart and it will automatically return to the front switch.

The most common cause for getting multiple copies of a server is using the socket manage RESTART button, which is flaky at best. Don't do this.

DBADD is a command entered in a terminal window that allows you to add a star to the CHARA database or look up a name of a star, nova or AGN to see if it already has a CHARA number. Valid requests can look like dbadd Vega or dbadd HD 123456. Identifiers for a target can be a common name, an IRC, HR, HD, SAO, FK5, HIP, GJ, or 2MASS designation. If a star, AGN or nova is in the database, it will return a CHARA number.\\ \\ __Targets that are not in the CHARA database__\\ \\ If a star, nova or AGN is not in the CHARA database, dbadd will query the SIMBAD database to see if it can be found there.

- | * The browser will prompt you for the admin user name and password. If these entries are not already filled in, then look for this information on the papers near the console. | + | |
- | * If the browser does not open, then check if there are other instances of firefox already running. To do this, open a terminal window, type "ps auxw | grep firefox", | + | |
- | * When the VPN connection is working, it will report "Phase 1: M-ESTABLISHED / Phase 2: ESTABLISHED" | + | |
